SOLUTION: A nozzle 26 is installed on a box 25, an exhaust pipe 27 is connected thereto, an aluminum flat plate 28 is installed in the lower part of the box, and an earth 29 is connected to the plate. A high tension power supply 30 is connected to an outer wall of the nozzle 26, one end of a water feed pipe 31 is connected to the nozzle, a non-pulsating flow pump 32 is connected to the other end of the water feed pump 31, and a medical liquid tank 32 is connected to the inlet side of the pump 32. The pump 32 is driven to spray acid water 34 from the nozzle 26. Thus, charged particles of the medical liquid are blown in such a manner as to be wrapped in the air into the barn, and the charged particles are remarkably diffused to adhere to the floating particles in the air in the barn, thereby efficiently sterilizing and deodorizing the air in the barn.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for disinfection and deodorization of a room for spraying and dispersing charged fine particles of a chemical solution to sterilize the room and, if necessary, deodorizing the room to keep the number of bacteria in the room constantly. Related to the device.

[0002]

2. Description of the Related Art Conventionally, there has been known an electrostatic spraying method for imparting an electric charge to drug solution particles in order to attach a drug solution to the back of leaves of vegetables and other plants (for example, JP-A-61-227864, 1-33461). Also, a relatively low voltage electrostatic spraying method which has solved the problems of the above inventions has been proposed (JP-A-6-90647).

[0003] As for sterilization and insecticide in a room, spraying of chemicals by human power or machine has been performed as required.

[0004]

A conventionally known electrostatic spraying method aims at making a chemical solution adhere to leaves of a target object (vegetables or the like) or the like to prevent the onset of the disease or the propagation of pathogenic bacteria. Was aimed at. Further, general spray disinfection is disinfection of indoor floors, walls, and the like, and is performed, for example, in a livestock barn when no livestock are present.

The conventional disinfecting method has a problem that it is not possible to disinfect in the air or to continuously disinfect when there is a source of bacteria or the like in the room (for example, when livestock are present).

Further, when the indoor area is large, the conventional sprayer or the like has a short spray diffusion distance, so that manual spraying becomes indispensable in a livestock barn or the like, and spraying in an open space requires a large amount of consumption. There were also problems.

[0007]

SUMMARY OF THE INVENTION The present invention employs electrostatic spray diffusion and uses comprehensive air to dramatically increase the automatic diffusion distance, thereby completely eliminating the conventional problems. It is.

That is, the invention of the method is an indoor sterilization and deodorization method characterized by spraying and diffusing charged fine particles of a chemical solution into a room and attaching the charged fine particles to indoor floating particles to sterilize and / or deodorize. . Still another invention is a method for indoor sterilization and deodorization, characterized by spraying and diffusing charged fine particles of a chemical solution together with inclusive air into a room and attaching the charged fine particles to suspended particles in the room, wherein the charged fine particles of the chemical solution are indoors. Is sprayed and diffused together with the inclusive air, and the airborne particles are captured by the charged fine particles and adhered to the indoor wall.

The invention of another method is to enclose charged fine particles to form entrapped air, and to blow in entrained air while spirally flowing.

[0010] The invention of the apparatus is, for example, a means for atomizing a chemical solution and a means for applying electric charge in a cylindrical housing provided with an outlet for charged fine particles and pressurized air at one end and an air inlet at the other end. And an indoor air disinfection and deodorization apparatus characterized by sequentially installing an air feeding means. Further, the charge applying means is provided with a high-voltage electrode outside the chemical liquid nozzle, and provided with a blowing direction control means for the charged fine particles in the outlet of the charged fine particles.

In the present invention, the chemical solution is sprayed and diffused together with the inclusive air, so that the flying distance of the charged fine particles (for example, particles having a size of 10 μm or less) is greatly increased. For example, if the inclusive air is not used, the scattering distance is about 1 m, but by using the inclusive air, it can be spread to a distance of 2 m to 5 m.

That is, in the case of spraying, since the blowing speed is restricted by the weight of the fine particles, it does not diffuse far, but air has the same specific gravity as room air and diffuses relatively far. And if the air diffuses far,
With this, the charged fine particles also diffuse far. The charged fine particles also embrace suspended particles in the air while diffusing, and adhere to walls and the like. Therefore, not only sterilization of bacteria floating in the air, but also fine particles causing odor can be captured, and sterilization and deodorization can be achieved simultaneously.

In the present invention, when the entrapment air is spirally blown, the entrapment air spirally flows in the room, assists the diffusion of the charged fine particles, increases the chance of contact with the suspended particles, and improves the sterilization efficiency. it can. The chemical in the present invention is, for example, sodium hypochlorite water, hydrogen peroxide or ozone.

According to the apparatus of the present invention, the charged fine particles can be wrapped in the air flow and blown into the room as it is. Therefore, the charged fine particles diffuse relatively far, and as a result, the sterilizing and deodorizing efficiency can be improved.
